【従来の技術】図8は、従来の内視鏡用組織採取具として用いられているいわゆるメンギーニ組織採取針の先端部分を示しており、棒状の針軸10の先端には尖った針先11が形成されると共に、切り取った標本組織を収納するための組織収納凹部12が、針先11の近傍を側面から凹ませた形状に形成されている。 BACKGROUND ART FIG. 8, a conventional endoscope shows the tip portion of the so-called Mengini tissue sampling needle, which is used as a mirror for tissue collecting device, the tip of the needle shaft 10 of the rod-like pointed needlepoint 11 There while being formed, the tissue storage recess 12 for accommodating the cut specimen tissue is formed into a shape by recessing the vicinity of the tip 11 from the side.

【0003】そして、針軸10に軸線方向に進退自在に被嵌された外套管20の先端には、組織収納凹部12に入り込んだ組織を切り取るための環状の刃21が内周側に形成されている。 [0003] Then, the tip of the needle shaft 10 outer tube 20 which is fitted retractably in the axial direction, the annular blade 21 to cut the penetrated into the tissue receiving recess 12 tissue formed on the inner peripheral side ing.

【0004】図9と図10は、そのような従来の内視鏡用組織採取具を用いて生検組織を採取している状態を示しており、図9に示されるように、組織100に突き刺さした内視鏡用組織採取具の外套管20を少し引き戻して組織収納凹部12内に組織100の目標部分を入れ込み、次いで図10に示されるように、外套管20を瞬時に送り出して、組織収納凹部12内に入り込んでいる組織100から標本組織101を切り取る。 [0004] Figure 9 and Figure 10 shows a state of such a collection of conventional endoscopic tissue collecting device biopsy tissue using, as shown in FIG. 9, the tissue 100 the pierced the endoscopic tissue collecting device to the mantle tube 20 slightly pulled back target portion of the tissue 100 to tissue receiving recess 12 of the-inserting, then as shown in FIG. 10, it turned out mantle tube 20 instantly, tissue cut sample tissue 101 from tissue 100 that enters the housing recess 12.

【0005】 [0005]

【発明が解決しようとする課題】しかし、上述のように用いられる従来の内視鏡用組織採取具では、組織収納凹部12の大きさより大きな標本組織を採取することができないだけでなく、実際には図11に示されるように組織収納凹部12内には標本組織101との間に空間ができ、また図12に示されるように外套管20を押し込んで標本組織101を切り取る際に、標本組織101が外套管20で押しやられて組織収納凹部12内から浮き上がってしまい、組織収納凹部12に比べて相当に小さな標本組織101しか採取することができなかった。 [0006] However, in the conventional endoscopic tissue collecting tool used as described above, not only can not be taken large sample tissue than the size of the tissue receiving recess 12, actually when cutting the specimen tissue 101 by pushing the outer tube 20 as is possible is a space between the specimen tissue 101 to tissue storage recess 12 as shown in FIG. 11, also shown in FIG. 12, sample tissue 101 is pushed by the outer tube 20 will be lifted from the tissue receiving recess 12 inside, could not only significantly small sample tissue 101 is collected as compared to the tissue storage recess 12.

【0006】そこで本発明は、装置を大きくすることなく十分な量の標本組織を容易に採取することができる内視鏡用組織採取具を提供することを目的とする。 [0006] The present invention aims to provide an endoscopic tissue collecting tool which can be easily collected a sufficient amount of sample tissue without enlarging the device.

【0007】 [0007]

【課題を解決するための手段】上記の目的を達成するため、本発明の内視鏡用組織採取具は、前方に向けて針先が形成されると共に、その針先の近傍部分を側面から凹ませた形状の組織収納凹部が形成された針軸と、針軸に軸線方向に進退自在に被嵌されて組織収納凹部に入り込んだ組織を切り取るための刃が先端に形成された外套管とを有する内視鏡用組織採取具において、針軸内を通って後方から組織収納凹部内に達する吸引路を設けたものである。 To achieve the above object, according to an aspect of endoscopic tissue collecting device of the present invention, together with the needle tip toward the front is formed, from a side portion in the vicinity of the needle tip a needle shaft organization housing recess shape is formed which is recessed, and the mantle is blade for cutting a movably fitted to entering into the tissue receiving recess tissue axially needle shaft formed at the distal end tube in endoscopic tissue collecting tool having, is provided with a suction passage from the rear through the needle shaft reaches the tissue receiving recess.

【0008】そして、外套管の先端から針軸が任意の長さ突出した状態で外套管を針軸に固定することができる固定手段を設けると、必要に応じて針軸と外套管を一体の状態で操作することができる。 [0008] When provided with securing means for the outer tube in a state where the needle shaft from the tip of the mantle tube protrudes any length can be fixed to the needle axis, of integral needle shaft and trocar as required it is possible to operate in the state. また、外套管の先端が針軸に対して所定位置にあることを手元側で表示するための指標を設けるとよい。 Further, it is preferable to provide an indicator to display at hand side to be in the predetermined position with respect to the distal end of the mantle tube needle shaft.

【発明の実施の形態】図面を参照して本発明の実施の形態を説明する。 Referring to DETAILED DESCRIPTION OF THE INVENTION The drawings will be described embodiments of the present invention. 図1と図2は内視鏡用組織採取具の全体構成を示しており、図1は外套管20が所定の最先端位置まで押し出されて針軸10に吸引具50が接続された状態を示し、図2は、外套管20が手元側に引き寄せられた状態を示している。 Figure 1 and Figure 2 shows the overall configuration of an endoscopic tissue collecting device, the state in which the suction device 50 is connected 1 is extruded mantle tube 20 to a predetermined advanced position to the needle shaft 10 shown, FIG. 2, the mantle tube 20 indicates a state of being attracted to the proximal side. 図2では、吸引具50の図示が省略されている。 In Figure 2, the illustration of the suction device 50 is omitted.

【0010】針軸10の先端には、前方に向けて尖った無孔の針先11が形成されており、針先11の直後の部分には、組織を収納するための組織収納凹部12が、針軸10を側面から凹ませた形状に形成されている。 [0010] distal end of the needle shaft 10 is formed with a needle tip 11 of the pointed imperforate forward, in part immediately after the needle tip 11, the tissue storage recess 12 for accommodating the tissue , and the needle shaft 10 is formed in a shape recessed from the side.

【0011】そして、組織収納凹部12に連通する吸引路13が、組織収納凹部12より後方の針軸10内に全長にわたって形成されている。 [0011] Then, the suction passage 13 communicating with the tissue receiving recess 12 is formed over the entire length to the tissue storage recess 12 from the rear of the needle shaft 10. したがって、針軸10の組織収納凹部12より後方部分はパイプ状に形成されている。 Thus, the rear portion from the tissue receiving recess 12 of the needle shaft 10 is formed in a pipe shape.

【0012】針軸10には、外套管20が軸線方向に進退自在に略全長にわたって被嵌されている。 [0012] the needle shaft 10, the mantle tube 20 is fitted on over substantially the entire length retractably in the axial direction. 外套管20 The outer tube 20
の先端部分は先細りのテーパ状に形成されており、その結果、外套管20の内周先端部分が環状の刃21になっている。 The distal end portion of which is formed in a tapered tapered, so that the inner circumference leading end portion of the mantle tube 20 is in an annular edge 21.

【0013】外套管20は針軸10より僅かに短く(例えば2〜10cm程度短く)形成されていて、その手元側端部には、手動のロックネジ23が先端を針軸10の外周面に当接するように取り付けられている。 [0013] mantle tube 20 be formed slightly shorter than the needle shaft 10 (for example, about 2~10cm short), in its proximal end, a manual locking screw 23 is advanced to the outer circumferential surface of the needle shaft 10 equivalents It is mounted so as to be in contact.

【0014】したがって、ロックネジ23を締め込めば外套管20が針軸10に対して固定された状態になり、 [0014] Accordingly, in a state where the outer tube 20 when Kome tighten the lock screw 23 is fixed relative to the needle shaft 10,
ロックネジ23を緩めれば外套管20が針軸10に対して進退自在になる。 Mantle tube 20 is movable forward and backward relative to the needle axis 10 by loosening the lock screw 23. また、針軸10と外套管20の各手元側端部付近には、進退操作を行うための指掛け14, Further, in the vicinity of the proximal end of the needle shaft 10 and the outer tube 20, finger rest 14 for performing forward and backward operation,
